Print to Adobe PDF but hold in Print Queue to collect all PDFS to merge

In order for us to complete a process we are using PDF Creator's Wait and Collect feature which allows us to print but it stores it in a queue to merge all documents into 1 then we use Adobe Acrobat to insert digital signatures and etc. 

Is there way to print to the Adobe Pdf, and let the various documents wait in a queue then merge them at the same time? We have several documents that are pulled from various sources so it makes it time consumng going back and forth between Adobe Acroabat and PDF Creator.
